ABSTRACT
The cathode-ray tube (CRT) dominates the display field because of its performance, its cost, and the fact that it has been around for a long time and is thus a familiar, as well as a mature, technology. All displays must produce enough output that the user can see the result, and this output must be distributed over a significant area. The interaction of a pulsed display with pulsating ambient light can cause annoying “beats” between the two light sources. It has been reported that this is especially a problem in offices with fluorescent lighting, which pulses at twice the power-line frequency. The CRT can deliver all the energy needed to excite a pixel for the entire frame time in a single pixel time, thanks to the high energy density in the electron beam. Although this is called multidimensional, the physical components of the display are arranged in a two-dimensional plane, unlike the Digisplay, which is a “true” three-dimensional system.
